For this listing, I have only replaced the outer blade. The inner blade was used for about 2 years. I am listing this because I received a new one. It's been about 2 years since I purchased it new (manufactured in 2020). As expected, Maxell's 5-blade shaver is different. The unique, heavy vibration is pleasant.
